FASTENER-INSERTING' DEVICE;

' To all'whom it mag concern.

Be it known that I, THOMAS J. J oHNs'roN, of White PlainsfWestchesterOoimty,-New York, have madecertain new and useful Improvements inFastener-Inserting- Devices, of which the following is a specification.

My present invention relates to fastener inserting devices for attachingfasteners to fabrics, leather or the like, particularly where there areseveral layersof the mathe flange which the set forms from the skirtterial. It is particularly "adapted to setting blind eyelets in shoeuppers, .where there are several assembled layersof liningand leather.While that is its principal utility, the principles here disclosed maybeemployed in securing other fasteners to some of several layers ofmaterial; 'someof-the claims forming part of this specification are sophrased, and are intended to cover such other applications of theinvention. The principal parts employed are a set for upsetting theskirt of the eyelet, where the device is so used, which has the usualtapered portion for that purpose; another member movable relative'to theset, which is prefer-l ably a sleeve, though it need not necessarilysurround the set; means movable relative to theset for'separating two ofthe'layers of material so as to provide a spacein which of the eyeletcurls over without engaging the outer separated layer, which means' isusually one or more levers pivoted in the sleeve, and operated by a camsurface on the punch'when the sleeve and punch'move relatively, thoughother arrangements may be employed. I Some means of returning the partsto normal position when the'Set is retracted is desirable, for whichsprings may be used. The device is positively actuated in its operation,which is to be preferred, as the action does not then. depend, as insome other devices, upon the resilience of the leather or othermaterial; but the layer is positively raised and after the eyelet is setis pressed down into place. In practice the layer moved is the outerone, and it is lifted by the levers as the work is commonly done; Iprefer to use the term separated in the claims, to cover inversions orlike ,wariations.

The accompanying drawing shows an embodiment of my invention in oneform, being a central vertical section of my improved device, on a largescale.

The set which upset-s the eyelet, which it is unnecessaryto show, bearsin general the reference letter A, with various -'indices.'

The conoidal part for upsetting is marked A; A isthe tapered shank".for-insertion in the machine commonly, employed; A a

collar; he 'sha'ft'of the Set, A the cam i y for operating the levers;while at A I show'that the tip may be inserted-in the shaft by ascrew-thread, thus making it re newable, and saving expense in .case' ofbreakage. As it is small, it may ybeimadea.

of good steel without undue cost.

' Bis the member carrying the levers,whi'ch is preferably a sleeve, andmay be formed integral if desired, as the removable. tip permits theinsertion of the set from above,

after the levers are secured in placefl C C are the levers forseparating-the layers of material, also not shown. I These are pivotedrespectively at 0 0", and are preferably e1- wedge-form. Also-it is bestto make the levers short andpivot them near the bottom of thesleeve, asthis makesthe radius of the are which they describe small, I and thusmakes them'lift; attheir outer ends more quickly, relative to theirlateral'swing, thus lifting th'e' outer layer-of leather'or fabricpromptly. A i v H H 1 F D D are springs for returning-the levers-totheir normal or lillustrated po'sitionjs asthe with'the charactero'f thework; With,ordi-.

nary leather two are sufficient; with very thin tawed skins three may beneeded, but more may be used, if desired, though not generally required.

I have drawn the view of the device on a much exaggerated scale, as isapparent, so as to make it easily comprehended.

Having thus described my invention, what I claim is:

1. A device for setting blind eyelets in a 7 selected part of severallayers of material,

comprising a set provided with a setting shoulder adapted for insertionin the material for spreading the skirt of an eyelet between two of thelayers, and means carried by the device and movable relatively to theset for sep arating: the tWo layers to permit the spread portion of theeyelet to pass be tween them.
